SUMMARY

The discussion centers on calculating the braking distance required to stop a 1500 kg car traveling at 30 m/s using a force of -9000 N. To solve this problem, one must apply Newton's Second Law to determine acceleration, followed by utilizing kinematic equations to find the distance. Specifically, the acceleration can be calculated as -6 m/s², leading to a braking distance of 45 meters when applying the appropriate kinematic formula.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with kinematic equations
  • Basic knowledge of force, mass, and acceleration
  • Ability to perform calculations involving units of measurement
NEXT STEPS
  • Study Newton's Second Law of Motion in detail
  • Learn how to apply kinematic equations for motion problems
  • Explore examples of calculating braking distances in physics
  • Investigate the effects of different forces on vehicle stopping distances
USEFUL FOR

Students in introductory physics courses, educators teaching mechanics, and anyone interested in understanding vehicle dynamics and stopping distances.

hi this is my first year in physics and i am already confused on it. I really need help on the following question: "The force of -9000 N is used to stop a 1500 kg car traveling at 30 m/s. What is the breaking distance is needed to bring the car to a halt?" I have no idea which formula to use or where to begin since i don't have the time or acceleration. Please help me. Thanks!

You have a force and a mass, you can find the acceleration using Newton's 2nd law.
 
you already have "v", once you find "a" you can use one of those kinematic equations to find "d".
 
Thanks A Bunch!
